4WE6D6X/EW110N9DK23L/V/62 CSA

The 4WE6D6X/EW110N9DK23L/V/62 CSA valve is produced by Bosch Rexroth within the WE Directional Spool Valves series. This solenoid-actuated unit directs pressurized oil to the selected working ports in hydraulic automation circuits. It uses a coil rated at 110 V AC for 50 or 60 Hz supplies, allowing direct connection to common control transformers. A continuous duty cycle of 100 % ED permits uninterrupted energization without thermal pauses. Ingress protection is specified as IP65 so the enclosure withstands dust ingress and water jets typically present near machinery. The mounting surface follows the ISO 4401-03-02-0-05 porting pattern, which standardizes interface dimensions on sub-plates. The valve sustains line pressures up to 350 bar on ports A, B, and P, enabling use in high-pressure hydraulic power units. Maximum flow capacity reaches 60 l/min, defining the upper limit for volumetric throughput at rated pressure differential. Reliable switching is maintained across fluid viscosities from 2.8 to 500 mm²/s, while permitted hydraulic fluid temperature ranges from −15 °C to +80 °C to cover most mineral oils.

Ambient air around the 4WE6D6X/EW110N9DK23L/V/62 CSA must remain between −15 °C and +50 °C so coil insulation and seals operate within design limits. All dynamic seals are made from FKM to resist the stated temperature band and common hydraulic media. Fluid cleanliness has to meet ISO 4406 (c) 20/18/15, limiting particle contamination that could accelerate spool wear. Electrical power reaches the solenoid through a DK23L three-pole Mini-Change connector, simplifying quick replacement during service. A concealed manual override identified as N9 lets maintenance staff shift the spool without energizing the coil. Tank port T can accept back pressure up to 160 bar, allowing remote return line restrictions or counterbalance valves. The complete assembly with two solenoids weighs 1.95 kg, light enough for manifold stacking without extra support brackets. A locating hole sized ISO 8752-3×8-St assists precise positioning on the sub-plate and prevents rotation during tightening.
